To calculate the mean of the salt concentrations, we add up all the values and divide by the number of values.
For the first set of data:
0.2 + 0.2 + 0.2 + 0.2 = 0.8
0.8 / 4 = 0.2
So the mean for the first set of data is 0.2 mol dm-3.
For the second set of data:
0.4 + 0.4 + 0.4 + 0.4 + 0.4 = 2
2 / 5 = 0.4
So the mean for the second set of data is 0.4 mol dm-3.
For the third set of data:
0.6 + 0.6 + 0.6 + 0.6 + 0.6 + 0.6 + 0.6 + 0.6 + 0.6 + 0.6 = 6
6 / 10 = 0.6
So the mean for the third set of data is 0.6 mol dm-3.
For the first set of data:
0.2 + 0.2 + 0.2 + 0.2 = 0.8
0.8 / 4 = 0.2
So the mean for the first set of data is 0.2 mol dm-3.
For the second set of data:
0.4 + 0.4 + 0.4 + 0.4 + 0.4 = 2
2 / 5 = 0.4
So the mean for the second set of data is 0.4 mol dm-3.
For the third set of data:
0.6 + 0.6 + 0.6 + 0.6 + 0.6 + 0.6 + 0.6 + 0.6 + 0.6 + 0.6 = 6
6 / 10 = 0.6
So the mean for the third set of data is 0.6 mol dm-3.
